FIELD OF THE INVENTION

The present invention relates to an infusion product for making abeverage, more specifically to a plant-based composition for making abeverage, and to a herbal and/or vegetable composition or bouquet garni,for food, medicinal or aromatic applications. The plants (raw materials)are fruits, herbs, medicinal plants, tea, vegetables and/or spices. Theinvention further relates to a method for producing said compositions orinfusion product, its use for making a (tea) beverage, and a (tea)beverage so obtained. Further, the present invention relates to afiber-web, preferably a tea bag, made from said fruits, herbs, medicinalplants, tea, vegetable and/or spices.

BACKGROUND OF THE INVENTION

A quick cup of tea, either from herbs, medicinal plants or tea plants(Camellia sinensis), also called “infusion” or “tisane” may be producedby putting conventional tea bags filled with parts of said fruits,herbs, medicinal plants, or tea (such as, for example, in the form ofleaves or powder) in a cup of hot or boiling water. For some teas, suchas fruit teas or teas made from herbs or medicinal plants, the steeptime is rather long, whereas for various kinds of tea plants,maintaining a certain steep time is required for producing the bestflavour. In some cases, there is either an incomplete extraction fromthe bag, resulting in a highly variable and generally weak flavoredbeverage, or an excessive extraction, resulting in a highly variable andgenerally strong or even bitter taste. The flavour and taste alsogreatly depends on water quality and temperature.

Similarly, herbs and spices are used for cooking, for example in a looseform or as a bouquet garni, or in the form of powders or bouillon cubes.However, broth made from rehydrated cubes is different in taste fromfresh broth because of its higher salt content and flavours changed bythe boiling process. Bouillon cubes are convenient and inexpensive buthave little nutritive value.

There is still a need to improve infusion products for making a teabeverage, in particular to allow for fast infusion that is moreindependent from external factors and temperature and suitable toprovide a more standardized beverage or herb-infused broth whileavoiding variable infusion results.

In a preferred embodiment of the invention, the plant is tea (Camelliasinensis), including white tea, yellow tea, green tea, oolong tea, blacktea, and/or pu-erh tea, and the like, including mixtures or blendsthereof.

In one embodiment, the composition of the invention (either for making adrink or as a mixture of herbs and spices) comprises a layer of fibrousplant product, wherein the fibrous plant product comprises a blend ofdifferent plants.

In one embodiment, the composition of the invention (either for making adrink or as a mixture of herbs and spices) comprises a plant extract,wherein the plant extract comprises a blend of different plants.

In another embodiment, the composition comprises a layer of fibrousplant product and a plant extract applied thereto, wherein the fibrousplant product comprises a blend of different plants and the plantextract comprises a blend of different plants, or wherein the fibrousplant product comprises a single plant and the plant extract comprises ablend of different plants, or wherein the fibrous plant productcomprises a blend of different plants and the plant extract comprises asingle plant.

In another embodiment of the composition, the layer of fibrous plantproduct and the plant extract are from the same plant or from differentplants.

In one embodiment of the invention, the layer of fibrous plant productof the composition comprises at least 70% (w/w) of fibrous plant productfrom one plant.

In one embodiment of the invention, the plant extract comprises at least70% (w/w) of a plant extract from one plant. In another embodiment, thecomposition comprises at least 70% of fibrous plant product, preferablywhere the at least 70% of a plant extract is from tea.

The herbal and/or vegetable composition is preferably a composition forculinary use or for use in cooking, i.e. as a herb and spice mixtureinstead of a conventional bouquet garni.

A conventional bouquet garni is a bundle of herbs usually tied togetherwith string and mainly used to prepare soup, stock, and various stews(herb and spice mixture). The bouquet is cooked with the otheringredients but is removed prior to consumption. Sometimes, the bouquetgarni is not bound with string but its ingredients are filled into asmall sachet, a net, or even a tea strainer, instead. Traditionally, thearomatics are bound within leek leaves, though a coffee filter (orcheesecloth) and butcher twine can be used, instead.

The herbal and/or vegetable composition or bouquet garni of theinvention may be used instead of a traditional bouquet garni. The herbaland/or vegetable composition or bouquet garni of the invention is eithermade from a single herb or vegetable (such as parsley, thyme, bay leaf,basil, burnet, chervil, rosemary, peppercorns, savory and tarragon,carrot, celery (leaves or stem), celeriac, leek, onion and parsley root)or from a mixture of herbs and/or vegetables. If a mixture of herbsand/or vegetables is used, the composition may be used as a new form ofa bouquet garni (“garnished bouquet”). In one embodiment, the herbs forthe bouquet garni of the invention are parsley, thyme and hay leaf. Inanother embodiment, and depending on the recipe, the bouquet garni mayalso include basil, burnet, chervil, rosemary, peppercorns, savory andtarragon. Vegetables such as carrot, celery (leaves or stem), celeriac,leek, onion and parsley root are sometimes included in the bouquet garniof the invention.

A further embodiment of the invention relates to a method for producingthe composition for making a beverage of the present invention. Forexample, the method comprises the steps of:

-   -   a) extracting components of at least one plant with a solvent;    -   b) separating the soluble portion (plant extract) from the        non-soluble portion (solid plant particles);    -   c) optionally refining the non-soluble portion;    -   d) preparing a sheet-like product from the non-soluble portion;    -   e) optionally concentrating the soluble portion;    -   f) applying the soluble portion of step b) or concentrated        soluble portion of step a) to the sheet of step d); and    -   g) drying the product of step f) to obtain the composition for        making a beverage.

In one embodiment of the invention, one or more plant components (plantmaterial or plant funish) such as, for example, stems, scraps, leaves,fines, dust and/or shorts, are initially mixed with a solvent (e.g.,water and/or other compounds) at elevated temperatures. For example,various solvents that are water-miscible, such as alcohols (e.g.,ethanol), can be combined with water to form an aqueous solvent. Thewater content of the aqueous solvent can, in some instances, be greaterthan 50% by weight of the solvent. In one embodiment, the water contentis 70%, 80%, 90% or 100%. Deionized water, distilled water or tap watermay be employed. The amount of the solvent in the suspension can varywidely, but is generally added in an amount from about 75% to about 99%by weight of the suspension. However, the amount of solvent can varywith the nature of the solvent, the temperature at which the extractionis to be carried out, and the type of plant components.

After forming the solvent/plant furnish mixture, some or all of asoluble extracts fraction of the furnish mixture may be optionallyseparated (e.g., extracted) from the mixture. If desired, the aqueoussolvent/plant furnish mixture can be agitated during extraction bystirring, shaking or otherwise mixing the mixture in order to increasethe rate of extraction. Typically, extraction is carried out for about0.5 hours to about 6 hours. Moreover, although not required, typicalextraction temperatures range from about 10° C. to about 100° C.

Prior to the extraction step an optional grinding or cutting step can beused, in order to shred the plant or plant part and thus to break theplant's cell walls.

Once separated from the insoluble residue fraction of the plantsolution, the soluble extracts fraction can optionally be concentratedusing any known type of concentrator, such as a vacuum evaporator. Inone embodiment, the soluble component may be highly concentrated.Moreover, the concentrated or unconcentrated soluble extracts fractioncan be utilized in any manner desired. For example, the soluble extractsfraction can be utilized as a flavouring material or a portion can beadded to the insoluble residue fraction.

Once extracted, the insoluble residue fraction can optionally besubjected to one or more mechanical refiners to produce a fibrous pulp.Some examples of suitable refiners can include disc refiners, conicalrefiners, and the like. The insoluble residue fraction can be utilizedin any manner desired. For example, the insoluble residue fraction canbe used as a flavouring material, used to produce a composition of theinvention, which is herein also referred to as reconstituted plantmaterial.

To produce a composition of the invention, the insoluble residuefraction is transferred to a papermaking station. The papermakingstation includes a forming apparatus, which may include, for example, aforming wire, gravity drain, suction drain, felt press, Yankee dryer,drum dryers, etc. In general, the insoluble residue fraction may be inthe form of a pulp. In the forming apparatus, the pulp is laid onto awire belt forming a sheet-like shape. Excess water is removed from thetobacco sheet using gravity drains, suction drains, presses, and dryers.Thereafter, if desired, a portion of the soluble extracts fraction maybe reapplied to the insoluble residue fraction. When the insolubleresidue fraction is recombined with the soluble extracts fraction, theresulting plant product is generally referred to as “reconstituted plantmaterial.”

Reconstituted plant material can generally be formed in a variety ofways. For instance, in one embodiment, band casting can be utilized toform the reconstituted plant material. Band casting typically employs aslurry of finely divided plant parts mixed with a binder such as gumarabic, guar gum, alginate, xanthan, cellulose and cellulose derivatives(such as carboxy methyl cellulose (CMC), hydroxypropyl methyl cellulose(HPMC)), pectines or starch that is coated onto a steel band and thendried. In one embodiment, the method is performed according to a processsimilar to the conventional tobacco reconstitution process, which is forexample described in U.S. Pat. Nos. 3,353,541; 3,420,241; 3,386,449;3,760,815; and 4,674,519; which are incorporated herein in theirentirety by reference thereto. The method for producing the products ofthe invention can also be performed by a papermaking process, in orderto reconstitute any plant components (such as stems, scraps, leaves,fines, dust and/or shorts) into a paper-like product. Some examples ofsuch processes are described in U.S. Pat. Nos. 3,428,053; 3,415,253;3,561,451; 3,467,109; 3,483,874; 3,860,012; 3,847,164; 4,182,349;5,715,844; 5,724,998; and 5,765,570; which are also incorporated hereinin their entirety by reference thereto for all purposes. For example,the formation of the products of the invention using papermakingtechniques can involve the steps of mixing fruits, herbs, medicinalplants, tea, vegetables and/or spices with water, extracting the solubleingredients therefrom, concentrating the soluble ingredients, refiningthe fruits, herbs, medicinal plants, tea, vegetables and/or spices,forming a web, reapplying the concentrated soluble ingredients, drying,and threshing.

In the method of the invention, more specifically with respect to thenon-soluble portion (solid plant particles) used in providing thenon-impregnated fiber web of the invention, ie. the sheet-like productin step d), the plant is not tobacco, wood pulp, cotton, textiles, juteflax, Indian hemp, hemp, hoopvine, kenaf, nettles, ramie, abacá, bamboofiber, banana (especially banana bark), bowstring hemp, coir (fiber fromthe coconut shell), esparto, henequen, kapok, milkweed, papaya, phormium(“New Zealand Flax”), sisal, raffia, bagasse, pina, aibika or yucca.However, a mixture of a plant mentioned hegira in connection with thepresent invention with any of the aforementioned plants may be utilized.Further to the foregoing listed materials also others materials can beadded to improve product physical characteristics, for example cellulosederivatives such as methylcellulose, carboxymethyl cellulose (CMC),hydroxypropyl methyl cellulose (HPMC), starch and starch derivativessuch as oxidatively degraded starch, polysaccharides (and theirderivatives) such as pectines, gelatins, guar gum, agar, alginates,carrageenans, or synthetic fibers such as the ones made of vinylchloride or vinyl acetate, polyethylene, polypropylene, polyesters.

Once extracted, the insoluble, solids portion can optionally besubjected to one or more mechanical refiners to produce a fibrous pulp.Some examples of suitable refiners can include disc refiners, conicalrefiners, and the like, well known to a skilled person. The pulp fromthe refiner can then be transferred to a papermaking station (not shown)that includes a forming apparatus, which may include, for example, aforming wire, gravity drain, suction drain, felt press, Yankee dryer,drum dryers, etc. In such a forming apparatus, the pulp is laid onto awire belt forming a sheet-like shape and excess water is removed by thegravity drain and suction drain and presses. Once separated from theinsoluble portion of the plant solution (plant extract), the solubleportion can optionally be concentrated using any known type ofconcentrator, such as a vacuum evaporator.

In some embodiments of the invention, a wet strength agent may be addedto the fibrous portion in order to reduce potential degradation of thereconstituted material when it is brought into contact with a liquid(e.g. water), such as upon infusion in water. Any suitable wet strengthagent preferably selected for food applications may be used such aspolyamide-epichlorohydrin resins, polyamine-epichlorohydrin resins,poly(aminoamide)-epichlorohydrin resins, urea-formaldehyde resins;melamine-formaldehyde resins; alkyl ketene dimer; alkyl succinicanhydride; polyvinylamines; oxidized polysaccharides (such asoxidatively degraded starch); glyoxalated polyacrylamide resins;polyimines such as polyethyleneimine. Wet strength agents are well knownto the skilled person and described in Ingredients Standards, such asBFR (Bundesinstitut für Risikobewertung) XXXVI and BFR XXXVI/1 or FDA(Food & Drug Administration) 21 CFR 176.170, FDA 21 CFR 176.110, FDA 21CFR 176.120, FDA 21 CFR 176.1180. The wet strength agent is for exampleused in an amount of about 0.1% w/w to about 20% w/w, preferably ofabout 1% w/w to about 10% w/w, more preferably of about 5% w/w. The wetstrength agent is preferably added to the fibrous portion when or beforemaking the sheet-like product (see step d) above).

In one embodiment, the water used for extraction is hot water,preferably of about 30 to 100° C., 40 to 90° C., or 50- to 80° C., ormore preferably of about 70° C.

In one embodiment, the coating ratio of solubles portion onto the fiberweb is about 5% to 80% (w/w), 10 to 70% (w/w), or more preferablybetween 20 and 50% (w/w). In some embodiments, the coating ratio orsoluble portion. that is added back to the base web (fiber web) issimilar to the portion of soluble material contained in and extractedfrom the original plant (so called “standard level”).

In one embodiment, the base weight of the final product is about 20 toabout 200 g/m² (dry basis), more preferably about 90 to about 120 g/m².

The extraction time depends on the fruits, herbs, medicinal plants, tea,vegetables and/or spices subjected to the extraction process. In oneembodiment of the invention, the extraction time is about 15 to 60minutes, preferably 45 minutes.

In one embodiment of the method of the invention, the extracting step isperformed using components of a blend of plants, in another embodiment,extracting step is performed using components of a single plant.

Extraction may also be performed by means other than using hot water,namely by extraction with supercritical gases, such as carbon dioxide,or by using, for example, ethanol, hexane, acetone, R134a(1,1,1,2-tetrafluoroethane), carbon dioxide and hydrofluorocarbons. Inone embodiment, the extraction can be carried out by using at least onesolvent at room temperature and under atmospheric pressure. Extractionmay also be performed by using a mixture of different solvents. Inanother embodiment, extraction may be performed using at least onesolvent, such as for example R134a or carbon dioxide, at differenttemperatures and at different pressures and different states (liquid orgaseous). For example, extraction may be performed using solvents in aliquid state (such as solvent that are volatile or non-volatile at roomtemperature), in a subcritical state (such as water at a temperatureabove 100° C. and a pressure above 1 bar), or in a supercritical state(such as carbon dioxide at a temperature above 31° C. and a pressureabove 73 bar).

Certain plants may require specific extraction conditions (time,temperature, solid/liquid ratio) due to the ingredients containedtherein, which may be temperature sensitive or must not be subjected tocertain extraction conditions. For example, extraction of lycopene fromtomatoes we must be performed by using specific enzymes to liberate theproduct from tomatoes cells. In connection with the present invention,processing aids maybe used to improve extraction, such as pH modifiers(such as, for example, NaOH or organic acids), microwaves, pressure,ultrasound, enzymes such as for example proteases, amylases, cellulases,and/or pectinases. Whenever reference is made herein to “extraction”,the term includes the aforementioned alternative extraction means. Theextraction used in connection with the present invention can beperformed in a continuous or discontinuous matter. The extractionconditions are well known to the skilled artisan and described instandard text books, such as Handbook of Separation Techniques forChemical Engineers, Third Edition (March 1997), Philip A. Schweitzer,McGraw-Hill Inc.

In one embodiment, the extraction and/or pressing may be performed usingat least a portion of the plant material, fresh, frozen or dried, orselected from roots, bark, seeds, stems, leaves, flowers and fruit.

Separation of the soluble portion (plant extract) from the non-solubleportion (solid plant particles) can be performed by separating theliquid phase from the solid phase, such as by filtration, with orwithout pressure, by centrifugation or other methods commonly used inthe laboratory and well-known to the skilled person.

In a preferred embodiment of the invention, the plant used in the methodof the invention is tea (Camellia sinensis), and the extraction isperformed for about 45 minutes with water at about 70° C.

In one embodiment of the method where a mixture or blend of plants isused, the non-soluble portion of the plant is mixed with the non-solubleportion of at least one further plant prior to preparing the sheet.

Certain embodiments of the method of the invention use the solubleportion of step b) or concentrated soluble portion of step e), which ismixed with the soluble portion or concentrated soluble portion of atleast one further plant prior to applying the soluble portion orconcentrated soluble portion to the sheet.

For certain applications it is desirable to adjust the composition byadding or removing ingredients or components to or from the plantextract and or the non-soluble plant particles prior to producing thefinal product of the invention. Such adjustment may be performed tomodify/improve chemical, physical and/or sensory characteristics of thefinished product. The invention thus encompasses methods, furthercomprising the step of adding or removing ingredients from the solubleportion (plant extract) and/or from the non-soluble portion (solid plantparticles) prior to applying the soluble portion of step b) orconcentrated soluble portion of step e) to the sheet of step d).

In some embodiments, the sheet or sheet-like product which is obtainedin step g) is a web or fiber-web. The sheet-like product or web may beused in different sizes and shapes. In some cases, the composition ofstep g) is further cut or broken into small regularly or irregularlyshaped forms. Alternatively, the composition is brought or formed intoany desired shapes, dimensions and formats, such as sheets, leafs (orleaf-like shapes), sticks, bands, cups, mugs, howls, flasks, kettles,bottles or the like, straws or tubes, discs or sheets and the like, asdescribed below. In addition to cutting or breaking the sheet or fibrousweb to a desired size and/or shape or forming the same into to a desiredsize and/or shape, it may be dried to the desired final moisturecontent.

In a preferred embodiment of the invention, the plant is tea (Camelliasinensis), including white tea, yellow tea, green tea, oolong tea, blacktea, and/or pu-erh tea, and the like, including mixtures or blendsthereof.

In a further embodiment, the invention relates to a fiber-web comprisingfrom about 5% to about 100% (w/w)), preferably at least 10%, at least20%, at least 30%, at least 40%, at least 50%, at least 60%, at least70%, at least 80%, at least 90%, or 100%, fibers of fruits, herbs,medicinal plants, tea, vegetables and/or spices. In one embodiment, thefiber-web further comprises cellulosic and/or synthetic fibers, andfibers of fruits, herbs, medicinal plants, tea, vegetables and/or spicesin a ratio of for example: 40/60 (w/w), 60/40 (w/w) or 20/80 (w/w). Inanother embodiment of the invention, the fiber-web of the presentinvention is obtainable by the method disclosed herein, namely as anintermediate product in step d) of the said method.

The invention further relates to a composition for making a beverage(drink, tea etc.), obtainable by the method of the present inventiondisclosed herein.

The invention also includes the use of the composition of the inventionfor making a beverage (drink, tea etc.), or broth, or for culinary useor use in cooking, respectively, i.e. as a herb and spice mixture suchas a bouquet garni instead of a conventional bouquet garni, as describedin this description. Specifically, the invention includes the use of thecomposition of the invention for as a drink (beverage), as a food orfood product, for culinary or cooking purposes, or for medicinal oraromatic applications and the like, as described above and in thefollowing description and examples.

Also included is a beverage obtainable by contacting water with thecomposition of the invention.

In one embodiment of the invention, the fiber-web comprises from about5% to about 100% (w/w)), preferably at least 10%, at least 20%, at least30%, at least 40%, at least 50%, at least 60%, at least 70%, at least80%, at least 90%, or 100%, fibers of fruits, herbs, medicinal plants,tea, vegetables and/or spices. For certain applications, the fiber-webmay further comprise cellulosic and/or synthetic fibers. In a particularembodiment, the fiber-web comprises fibers of (i) fruits, herbs,medicinal plants, and/or tea, vegetables and/or spices and (ii)cellulosic fibers and/or synthetic fibers in a ratio of 40/60 (w/w),60/40 (w/w) or 80/20 (w/w).

The invention further relates to a fiber web, obtainable by the methodof the invention, namely in step d).

In some embodiments of the invention, the fiber-web further comprises acoating or impregnation with soluble portion (plant extract) of fruits,herbs, medicinal plants, or tea.

The coating or impregnation is obtained by various methods known to theskilled person, such as applying to or treating the fiber-web orsheet-like structure with a plant extract, such as in a bath or byspecial application means, such as sprayers. In addition, various otheringredients, such as flavor or color treatments, can also be applied tothe web. If applied with the soluble portion and/or other ingredients,the fibrous sheet material can, in some embodiments, then be driedusing, for example, a tunnel dryer, to provide a sheet having a typicalmoisture content of less than 20% by weight, and particularly from about9% to about 14% by weight.

The invention thus also relates to an impregnated or coated fiber-web,obtainable by the method of the invention, namely in step g).

According to a further embodiment, the fiber-web of the inventionfurther comprises a coating or an impregnation with the soluble portion(plant extract) of said fruits, herbs, medicinal plants, or tea. Inanother embodiment of the invention, the fiber-web of the presentinvention is obtainable by the method disclosed herein, namely as theend product in step g) of said method.

In a further embodiment, the invention relates to a tea. product orcontainer, which is a tea bag comprising the fiber-web referred toherein, which is either impregnated with the soluble portion (plantextract) of said fruits, herbs, medicinal plants, or tea, or which isnot impregnated. The tea bag may be empty or filled, ie. the tea bag mayfurther comprise inside a sample or portion of fruits, herbs, medicinalplants, or tea, such as in the form of tea leaves, tea dust or the like.Even though the tea bag may be produced industrially on conventional teabagging machines, in this embodiment, the product is made from entirelynatural products, most preferably the same plant or herb as the one usedfor making the beverage, wherein the product avoids using conventionalcellulose-based tea bags.

In one embodiment, the tea bag may be impregnated with tea extract,wherein said product provides an increased tea aroma when making theinfusion, in particular when the tea bag is filled with, for example,tea leafs or tea dust. In a preferred embodiment, the tea bag comprisingthe fiber-web referred to herein, is impregnated with the solubleportion of a certain kind of tea (tea extract) and also filled with thesame kind of tea, for example in the form of tea leafs or tea dust.Alternatively, the impregnation can be made using a different plant orherb as used for the filling of the bag, such as, for example, the rindof the bergamot orange, a fragrant citrus fruit typically used toprovide the distinctive flavour and aroma of Earl Grey tea. In thiscase, Earl Grey tea products can be prepared from unflavoured tealeaves, simply by adding the flavour and aroma of the bergamotte orangein the form of the tea bag coating. This procedure facilitates theproduction process, as the tea company is not required to aromatizedifferent batches of tea but can simply use non-aromatized tea instead,the latter of which is packaged into tea bags specifically aromatizedusing different impregnations. In another embodiment applying thisprinciple, a mixture of teas and/or other plants can be utilized formaking tea bags, where tea is placed into the tea bag, wherein the teabag is made, for example, of mint leaves.

Alternatively, the tea product or container of the invention is providedin the form of a tea pod, tea pad or tea capsule instead of a tea bag,such as for either direct immersion or to be used in connection withconventional tea machines or coffee brewing machines (such as NestléSpecial.T®, or Nespresso®).

The products of the invention enable a more efficient infusion (100%solubles are extracted from the plant) in the sense that more solublescan be released than natural plant ingredients for a given weight ofmaterial. The products also provide a faster infusion (than with aconventional infusion made from the vegetal material in its natural nonconverted form). Specifically, the compositions of the invention haveimproved efficiency in boiling water or in non-heated water or water atroom temperature.

The process for making the compositions of the invention also allows forspecifically adjusting the final composition of the products, such as toremove from the soluble or the non-soluble portion(s) for exampleforeign matters, components altering taste and/or odor, or caffeine,nicotine, pesticides, aluminum, heavy metals, mycotoxins, toxicants andallergenic molecules such as coumarin, farnesol, geraniol, limonene,linalol, safrole, methyleugenol, or by adding to the soluble or thenon-soluble portion(s) for example desirable additives, such assweeteners, sugars, flavors, casings, vitamins, colorants, minerals,taste enhancers.

In another embodiment, the soluble portion in the reconstituted materialof the invention can be precisely adjusted (decreased as compared tostandard level, at standard level, or increased as compared to standardlevel). A key benefit is that the level of ingredients in thereconstituted material can be precisely increased to a level higher thanin the original natural form, thus allowing for more concentrated (moreintense) drinks, teas or broths. The adjustment of ingredients can alsoguarantee a consistent, standardized level of delivered ingredients tocompensate natural variations of active ingredients in plants.

Preferably, the method of the invention also allows for reduction ofundesired compounds from the material, such as to selectively removeundesired components (such as, for example but not limited to, naturalingredients, caffeine, nicotine, aluminum, heavy metals, pesticides,impurities or the like). For example, it is possible to removecomponents from either the soluble portion (plant extract) or from thenon-soluble portion (solid plant particles) or both by liquid-liquidextraction, physical adsorption, centrifugation, chromatography,crystallization, decantation, by use of a demister, drying,distillation, electrophoresis, elutriation, evaporation, solid phase orliquid-liquid extraction, flotation, flocculation, filtration (forexample using membranes), vapor-liquid separation, and/or sublimationand other means well known to the skilled person, preferably beforeapplying the plant extract to the base web.

In connection with adding ingredients, extracts of different sources andorigins, flavors, coloring agents or the like may be used, such asclorophyll, anthocyans, caramel, caroteinoids. For example, when usingtea or herbs it is possible to include L-menthol at various quantities(such as 6% or 15%) in the finished product. Products so obtained have adistinctive taste and aroma of menthol. In one embodiment, eugenol,thymol or plant extracts/concentrates can be added to the reconstitutedbouquet garni of the invention.

The present invention also allows to blend various plants and herbs. Inone example, instead of using single plants, such as tea or mint leaves,tea may be replaced by a mixture of, for example, 50% tea and 50% mintleaves (w/w); 50% verbena and 50% mint (w/w); 30% cinnamon and 30% teaand 10% licorice and 10% chamomile and 10% red vine and 10% roobois(w/w); and many other combinations.

The combination of different plant materials through the reconstitutionprocess into a single fiber web impregnated with extracts from differentplants (the same plant or blends) offers new taste experiences andadditive or synergistic effects. For example, it is known thatcombinations of certain plant extracts or combinations of certain plantingredients have additive or synergistic effects, such as, for example,a mixture of hops and valerian extracts for use in treating insomnia andvigilance (Blumenthal and al., J. Herbal Medicine, expanded Commission Emonographs, American Botanical Council, Austin, 2000, 394-400), ormixtures of oregano and cranberry extracts for use in treating H. pyloriinfections (Lin et al., Appl. Environ. Microbiol. December 2005, vol.71, no. 12, 8558-8564), or different mixtures of extracts of S.baicalensis, D. morifolium, G. uralensis and R. rubescens tested fortheir additive or synergistic effect in prostate cancer cell lines(Adams et al., Evid Based Complement Alternat Med. 2006 March; 3(1):117-124).

In the context of the present invention, the reconstituted plantmaterial or product of the invention may be used to blend a single plant(or a mixture of different plants) together with natural materials, suchas, for example, reconstituted black tea with natural tea material orreconstituted mint (Mentha spp.) with natural green tea material, inorder to improve the quality (such as the chemical constitution, theconsistency or sensory profile and characteristics) of the product orblend.

It has been found that some beverages are particularly less astringentand bitter when prepared from the reconstituted plant material orproduct of the invention as compared to original material from which thereconstituted plant material or product of the invention was prepared.This is, for example, the case for green tea, which is less astringentand bitter when made from a reconstituted green tea product according tothe invention as compared to a conventional infusion of green tea.

The production method also provides for reducing microbiological load ofthe final products because of the high temperatures during thepapermaking process.

The products of the invention provide a light material having a smallsurface, which allows economic packaging/shipping. For the consumer, theproducts of the invention are easy to transport and easy to use.Specifically, it has been found that the products of the invention areeasily infusible in even cold water. This has particular advantages forconsumers in cases where no heating or electricity is available forpreparing hot water.

The products are further available in all shapes, dimensions andformats, such as sheets, leafs (or leaf-like shapes), sticks, bands,cups, mugs, bowls, flasks, kettles, bottles or the like, straws ortubes, discs or sheets and the like, and can be customized with a logo.These products are convenient for the customer to be put or dipped intohot or cold water to produce the beverage of interest. Alternatively,hot or cold water is poured into or injected into said cups, mugs,bowls, flasks, kettles, bottles or the like, to produce the beverage ofinterest. In the case of straws or tubes impregnated with the desiredplant extract on the inner side of the stave or tube, infusion occurswhen sucking cold or hot liquid (e.g. water) through the straw or tube.Alternatively, the straw or tube is simply placed in cold or hot water,such as for example in a kettle or glass, to produce the beverage orbroth of interest. In the case of cups, mugs, bowls, flasks, kettles,bottles or the like, preferably (only) the inner side of the cups, mugs,bowls, flasks, kettles, bottles or the like are impregnated with theplant extract of interest. By pouring cold or hot liquid (such as water)into the cups, mugs, bowls, flasks, kettles, bottles or the like,immersion and infusion take place to provide the beverage or broth ofinterest. In one embodiment of the invention, the cups, mugs, bowls,flasks, kettles, bottles or the like are entirely made of the productsof the invention, i.e. made of the composition of the inventioncomprising a layer of fibrous plant product and a plant extract appliedthereto. In this case, the cups, mugs, bowls, flasks, kettles, bottlesor the like are preferably disposable. Thus, the customer would simplyneed cold or hot liquid, such as cold or hot water, to make theinfusion, beverage or broth of interest. In an alternative embodiment,the products of the invention, i.e. the compositions of the inventioncomprising a layer of fibrous plant product and a plant extract appliedthereto, form the inner coating or lining of cups, mugs, bowls, flasks,kettles, bottles or the like. These products may be provided either asdisposable, such as (bio-)degradable, or as non-disposable products,depending on the material used for producing the cups, mugs, bowls,flasks, kettles, bottles or the like. Also, the inner coating or liningof cups, mugs, bowls, flasks, kettles, bottles or the like may either bein the form of a permanent coating or lining, i.e. fixed to the innerwalls of said cups, mugs, bowls, flasks, kettles, bottles or the like,or it may be in the form of a replaceable product (like a cartridge)having the same shape as the cup, mug, bowl, flask, kettle, bottle orthe like, in order to he disposed of after use (i.e. after preparing theinfusion, beverage or broth) and replaced by a new product in order toprepare a new infusion, beverage or broth.

In one embodiment of the invention, the products are provided in theform of kits comprising said sheets, leafs (or leaf-like shapes),sticks, bands, cups, mugs, bowls, flasks, kettles, bottles or the like,straws or tubes, discs or sheets and the like. In one embodiment, thekits may also comprise extracts of plants of interest, suitable for thecustomer to impregnate said products before making the desired beverageor broth (i.e., first-time impregnation), or to re-impregnate saidproducts after use to make further beverages or broths (i.e., reusableversion of a product that was already pre-impregnated before its firstuse). In one embodiment of said kits, the kits comprise various types ofplants of interest, i.e. various different fruits, herbs, medicinalplants, tea, vegetables and/or spices, in order to enable the customerto make his/her own blends as desired. In this way, the customer is ableto create his/her flavor or taste. In these kits, the different types ofplants may be in the form of different sheets, leafs (or leaf-likeshapes), sticks, bands, cups, mugs, bowls, flasks, kettles, bottles orthe like, straws or tubes, discs or sheets and the like, separatelypre-impregnated with said different fruits, herbs, medicinal plants,tea, vegetables and/or spices. Alternatively, the different fruits,herbs, medicinal plants, tea, vegetables and/or spices may be providedin the kits in the form of separate plant extracts (or pre-mixedcombinations), in order to be used for re-impregnation as describedabove.

In one embodiment, where the products of the invention are provided inthe form of sheets like sheets of paper, impregnated with the plantextracts of interest as described above, the sheets may form separatepages and be put together like pages of a book. For example one or morepage of said book may be impregnated with one type of plant (fruit,herb, medicinal plant, tea, vegetable and/or spice), whereas other pagesare impregnated with different types of plants (fruit, herb, medicinalplant, tea, vegetable and/or spice). The pages that are impregnated witha certain plant extract, wherein the extract comprises the extract ofeither a single plant or a blend of plants, may contain a description ofsaid plant(s) used for the impregnation of said page. The descriptionmay be written on or printed to said page using food inks or food dyes.In a preferred embodiment of the “book” described above, the book is a“tea book”, where the impregnations on the individual pages are extractsof different types of tea, wherein separate pages correspond to separatetypes of tea or blends of tea containing said description of theoriginal tea product used for making the sheets and/or theimpregnations. The sheets or pages of the book are suitable for thecustomer to be used for preparing infusions, beverages or broths. In oneembodiment, the pages of the book may be perforated for easy detachingthe pages from the book.

Referring to FIGS. 19A thru 19K, various embodiments of products made inaccordance with the present disclosure are illustrated. For instance,referring to FIG. 19A, an infusion product dispenser 10 is shown. Theinfusion product dispenser 10 includes a dispenser housing 12 containingan infusion product 14. The infusion product 14 is contained within thedispenser housing 12 and dispensed through an opening or slot 16. Theinfusion product 14 comprises a layer of fibrous plant product in whicha plant extract has been applied thereto. In the embodiment illustratedin FIG. 19A, the infusion product 14 is in the form of a strip orstrips. For instance, in one embodiment, the infusion product 14 maycomprise a single strip that is spirally wound within the dispenserhousing 12. In this embodiment, a user can pull from the dispenserhousing 12 a desired amount of the infusion product 14 for producing atea or beverage. In one embodiment, the infusion product 14 can be tornor ripped when a desired amount has been withdrawn from the dispenserhousing 12. Optionally, the dispenser housing 12 may include a cuttingdevice for cutting the infusion product 14 as the product is beingdispensed. For example, in one embodiment, the cutting device maycomprise a serrated edge located within or adjacent to the opening orslot 16.

In an alternative embodiment, the infusion product 14 may includeperforation lines at periodic intervals. In this embodiment, whenremoving the infusion product 14 from the dispenser housing 12, adesired portion of the infusion product can be easily detached from theremainder of the strip by tearing along one of the perforation lines.

In still another embodiment, the infusion product 14 may be precut intostrips having a desired length. The individual strips can then be heldwithin the dispenser housing 12 in any suitable arrangement. Forinstance, the strips can be stacked within the dispenser housing or canbe spirally wound together. When cut into individual strips, the stripscan be arranged within the dispenser housing such that when one strip isremoved from the dispenser housing 12, an adjacent strip automaticallypartially protrudes from the dispenser housing through the opening orslot so that the next strip is accessible for use. In this regard, theindividual strips of the infusion product 14 can be interconnectedtogether using, for instance, an adhesive material and/or through afolding arrangement.

In one particular embodiment, the infusion product 14 can be containedwithin the dispenser housing 12 in the form of individual strips. Asshown in FIG. 19A, each strip can include a tab portion 18 located atone end of each individual strip. The tab portion 18 can be used forholding and manipulating the infusion product 14 without touching thereconstituted material. The tab portion 18 can be formed in variousways. For instance, in one embodiment, the tab portion 18 may comprise acoating that has been applied to the strip of reconstituted material.The coating can be made, for instance, from a polymer, such as afilm-forming polymer. Alternatively, the tab portion 18 can be formed bylaminating a sheet or film to the strip of reconstituted material. Inthis embodiment, the layer or sheet laminated to the reconstitutedmaterial may comprise a paper, a polymer film, or the like. In stillanother embodiment, the tab portion 18 can be made from a differentmaterial than the reconstituted material and then attached to the stripof the reconstituted material. In this embodiment, the tab portion 18can he attached to the reconstituted material using any suitableadhesive. The tab portion 18 can be formed from a film, a paper, anonwoven web, a woven web, a knitted web, or the like.

In one particular embodiment, the tab portion 18 can comprise anadhesive portion for not only manipulating the infusion product 14 butalso for adhering the infusion product 14 to an adjacent surface. Anadhesive portion can be formed by applying an adhesive material to thestrip of reconstituted material or to a different material that isattached to the strip of reconstituted material. The adhesive portion 18comprises an adhesive material that is completely non-toxic and safe forcontact with food products.

As shown in FIG. 19A, the tab or adhesive portion 18 is located at oneend of the strip of infusion product 14. In one embodiment, the tab oradhesive portion 18 forms an end tab at the end of the infusion product14. The tab or adhesive portion 18 generally has a length that is lessthan 50%, such as less than 40%, such as less than 30%, such as lessthan 20%, such as less than 15%, such as less than 10% of the totallength of the strip. The tab or adhesive portion 18 is generally greaterthan about 2%, such as greater than about 5% of the entire length of thestrip.

The adhesive portion 18 can have various different functions whenpresent in conjunction with the infusion product 14. For instance, asshown in FIG. 19A, the adhesive portion 18 can be used to adhere theinfusion strip product 14 to a coffee cup or mug so that the infusionproduct remains in a certain position while the cup or mug is filledwith a liquid, such as cold or hot water. Once a beverage is made fromthe infusion product, the infusion product can be easily removed fromthe cup or mug by grasping onto the adhesive portion 18. In this manner,the infusion strip product 14 can be easily attached during use andeasily detached after use during the production of a beverage.

In addition to attaching the infusion strip product to an adjacentsurface, the adhesive portion 18 can also be used to facilitate themanner in which the strip product is dispensed from the dispenserhousing 12. The adhesive portion 18, for instance, can allow each of theindividual strips to be temporarily attached together within thedispenser housing 12 within a stack. By interconnecting the individualstrips, when one strip is removed from the dispenser housing, anadjacent strip can be pulled through and immerge from the opening 16. Inthis manner, the individual strips can be easily dispensed from thedispenser housing one at a time.

The adhesive portion 18 can be formed in different ways. In oneembodiment, the adhesive portion 18 can be formed by simply applying theadhesive material to a portion of the infusion product strip.Alternatively, the adhesive portion 18 may comprise a substrate treatedwith the adhesive material and then attached to the infusion stripproduct. In one embodiment, the adhesive portion 18 may further includea release liner. The release liner may be used to cover the adhesivematerial prior to use. In this embodiment, when the infusion stripproduct is to be adhered to an adjacent surface, the release liner canbe peeled away and removed from the adhesive portion thereby exposingthe adhesive material.

Referring to FIG. 19C, another embodiment of an infusion productdispenser 10 is shown. The dispenser housing 10 includes a dispenserhousing 12 that dispenses an infusion product 14. In the embodimentillustrated in FIG. 19C, the dispenser housing 12 has a rectangularshape in comparison to the dispenser housing illustrated in FIG. 19Awhich has more of a cylindrical shape. In the embodiment illustrated inFIG. 19A, the infusion strip product is dispensed from the dispenserhousing in a length-wise direction. In the embodiment illustrated inFIG. 19C, on the other hand, the infusion strip product 14 is dispensedfrom the dispenser housing 12 in the width direction.

Otherwise, the embodiment illustrated in FIG. 19C can be constructedsimilar to the embodiment illustrated and described above with respectto FIG. 19A. In the embodiment illustrated in FIG. 19C, for instance,the infusion product 14 can comprise a single strip of product containedwithin the dispenser housing 12 or can comprise individual stripsstacked within the dispenser housing. When a single strip is containedwithin. the dispenser housing 12, the strip can be periodicallyperforated to allow a user to remove from the strip an individual stripproduct. Alternatively, the dispenser housing 12 can include an openingor slot 16 that is positioned adjacent to a cutting device, such as aserrated edge 22. The serrated edge 22 can be used to cut the infusionstrip product into individual strips having any desired width.

As shown in FIG. 19C, the infusion product 14 includes an adhesiveportion 18 for adhering the strip product to an adjacent surface, suchas a cup or mug. In the embodiment illustrated in FIG. 19C, the adhesiveportion 18 includes a release liner 20 that covers and protects theadhesive material prior to use. The release liner 20 can be made, forinstance, from a film, such as a polymer film. In one embodiment, forinstance, the release liner 20 can comprise a polyester film. Once anindividual strip is removed from the dispenser housing 12, the releaseliner 20 can be peeled away from the adhesive portion 18 for adheringthe strip product to an adjacent surface.

Referring to FIG. 19G, another embodiment of an infusion productdispenser 10 similar to the embodiments illustrated in FIGS. 19A and 19Cis shown. Like reference numerals have been used to show the same orsimilar elements. As shown in FIG. 19G, the infusion product dispenser10 includes a dispenser housing 12 containing an infusion product 14 inthe form of a strip or multiple strips. The dispenser housing 12includes an opening or slot 16 through which the infusion product 14 isdispensed. The infusion product 14 can comprise a continuous or endlessstrip within the housing or can comprise individual strips that arestacked or otherwise interconnected within the housing. Each individualinfusion strip product 14 can include an adhesive portion 18 foradhering the infusion product to an adjacent surface, such as a cup ormug.

In the embodiment illustrated in FIG. 19G, the infusion product iscontained within the dispenser housing within a spirally woundarrangement either as a single strip or as multiple strips. In thismanner, each individual strip is dispensed from the dispenser housing ina curved configuration, such as a spiral configuration. As shown in FIG.19G, for instance, the spiral configuration is maintained when theinfusion product is placed in use. By having a spiral configuration orcurved configuration, the infusion strip product 14 conveniently fitswithin the cup or mug even when the strip has a length that is greaterthan the depth of the mug. For example, the embodiment illustrated inFIG. 19G is particularly well suited for embodiments where the strip 14has a length of greater than about 2.5 inches, such as greater thanabout 3 inches, such as greater than about 3.5 inches, such as greaterthan about 4 inches, such as greater than about 4.5 inches, such asgreater than about 5 inches, such as greater than about 5.5 inches, suchas greater than about 6.5 inches. The strip generally has a length lessthan 20 inches, such as less than 12 inches.

A liquid, such as hot or cold water, canbe placed in the mug or cup 50 for producing the beverage or broth. Thecylindrical member 42 can be used not only to produce the beverage orbroth, but can also be used to stir the solution during extraction. Whenin the form of a straw or tube, the cylindrical member 42 may also beused to drink the beverage or broth. Of particular advantage, furtherflavoring of the beverage or broth may occur as the solution is drawn upthrough the straw.

The cylindrical member 42 can have any suitable length, such as fromabout 4 inches to about 30 inches, such as from about 4 inches to about24 inches.

The cylindrical member 42 can be formed in various ways. In oneembodiment, for instance, the cylindrical member 42 can include aninfusion portion 52 connected to a handle portion 54. The handle portion54 is for handling the cylindrical member 42 without touching thereconstituted material. The handle portion 54 can comprise any suitablematerial. For instance, the handle portion 54 can be formed by coatingor covering the reconstituted material. For instance, the reconstitutedmaterial can be coated with a polymer, such as a film-forming solution.Alternatively, the reconstituted material may be covered with a papermaterial. In still another embodiment, the handle portion 54 can be madeexclusively from a different material and attached to the infusionportion 52. For instance, the handle portion 54 can be made from aplastic or paperboard material, such as materials that have been usedconventionally to make straws.

In one embodiment, one or more of the cylindrical members can bepackaged in a dispenser 56. In the embodiment illustrated in FIG. 19D,for instance, a plurality of the infusion products 40 can be placed inthe carton 56 for use by a consumer. The carton or package 56 caninclude a perforated portion 58 that can be removed for access to theproduct within the container. The package 56 can be made from paper, apaperboard, or from a plastic material, such as a rigid plastic or aflexible plastic film.

Referring to FIG. 19I, still another embodiment of an infusion product110 made in accordance with the present disclosure is shown. In theembodiment illustrated in FIG. 19J, the infusion product 110 comprises ashaker that is designed to produce a beverage, particularly a coldbeverage such as iced tea. The infusion product 110 includes a cup ortumbler 112. The cup or tumbler 112 includes a top 114. The top 114 canbe liquid tight such that the cup or tumbler can be filled with aliquid, covered with the top, and shaken without any liquid release orleaking. The top 114, for instance, may include a gasket made from anelastomeric material to ensure a liquid tight seal. The top 114 can fitover the cup 112 using threads or can have a tension fit.

In accordance with the present disclosure, the cup or tumbler 112 isused in conjunction with an infusion member 116. The infusion member 116can be made from the reconstituted material in accordance with thepresent disclosure and may comprise a fibrous plant product that hasbeen treated with a plant extract. The infusion member 116 can have anysuitable shape. In the embodiment illustrated in FIG. 19J, for instance,the infusion member 116 is in the shape of a disk. It should beunderstood that the infusion product 110 can include a single infusionmember 116 or can include multiple infusion members. The infusion member116 illustrated in FIG. 19J is configured to have a diameter that isslightly smaller than the diameter of the cup or tumbler 112. In thisregard, the infusion member can be placed at the bottom of the cup ortumbler and generally match the diameter of the inside wall of the cupor tumbler.

Optionally, the infusion product 110 can include a baffle 118. As shownin FIG. 19J, the baffle can be circular in shape and generally haveapproximately the same diameter as the cup or tumbler. The baffle 118can comprise a perforated base. The baffle 118 is designed to fit overthe infusion member 116 to form a reservoir for the infusion member 116at the bottom of the cup or tumbler.

In order to produce a beverage, the infusion member 116 can be placed inthe cup or tumbler 112. If desired, the baffle 118 can be placed overthe infusion member 116. The cup or tumbler 112 can then be filled witha liquid, such as water. The top 114 can be placed on the cup or tumblerand the entire assembly can be shaken to form a beverage.

In one particular embodiment, after the infusion member 116 and baffle118 are placed in the cup or tumbler 112, the cup or tumbler can befilled with fresh water and possibly ice cubes. The infusion member 116can comprise a layer of fibrous plant product comprising a tea. In thismanner, the infusion member 116 can be used to produce a tea beverage,such as iced tea.

In one embodiment, instead of shaking the infusion product 110, the cupor tumbler can be filled with water and placed into a refrigerator withno ice cubes. Once refrigerated so that the water obtains a desiredtemperature, the cup or tumbler can be removed from the refrigerator andshaken to produce iced tea.

Yet another embodiment of an infusion product 120 made in accordancewith the present disclosure is illustrated in FIG. 19K. The infusionproduct 120 illustrated in FIG. 19K includes a plurality of infusionproduct dispensers 122. The infusion product dispensers 122 can beconfigured similar to the infusion product dispenser illustrated in FIG.19A, illustrated in FIG. 19C, or illustrated in FIG. 19G. Each infusionproduct dispenser can contain a reconstituted material in accordancewith the present disclosure. In this embodiment, each infusion productdispenser can contain a different product. For instance, each infusionproduct dispenser may contain an infusion member or strip made from adifferent type of tea or herbal tea. In this manner, a consumer has avariety of teas to select from in producing a beverage.

As shown in FIG. 19K, the infusion product dispensers 122 can be mountedonto a frame 124.

Referring to FIG. 21 , still another embodiment of an infusion product200 made in accordance with the present disclosure is shown. In thisembodiment, the infusion product 200 comprises a capsule 210 containingthe reconstituted material 212 of the present disclosure. The infusionproduct 200 is for producing a broth or beverage. In one embodiment, forinstance, the reconstituted material 212 comprises a tea or herbal teathat can be used to produce a tea beverage. The infusion product 200 asshown in FIG. 21 is particularly well suited to be used in connectionwith conventional single capsule coffee brewing machines.

Single chamber beverage capsules such as the one shown in FIG. 21 have asingle chamber defined by a plastic or aluminum body. As shown, thechamber contains the reconstituted material 212 for producing a beveragein a high pressure beverage preparing machine. Hot water is injectedunder pressure by the beverage preparing machine into the single chambercontaining the reconstituted material. As the pressure within thechamber increases, a capsule cover 214 is forced against raisedprojections in a capsule holder to the point that the projectionspenetrate the cover 214 so that the beverage flows through the cover andinto a user's cup.

One advantage of single serve beverage capsules is that each servingcontains a fresh supply of ingredients. The freshness of the ingredientscan be preserved through a modified atmosphere packaging process wherethe air within the capsule is modified such as by replacing the air withinert gas prior to sealing. The inert gas, for instance, may comprisenitrogen.

The capsule 210 illustrated in FIG. 21 includes a body that can be madeof aluminum and/or plastic and may be relatively stiff to preventcollapse, especially when the top is being perforated within thebeverage production machine. The top 214 can be made from a materialcapable of being pierced during production of a beverage. For instance,the top 214 can be made from a foil or a plastic film.

Optionally, the infusion product 200 can include a filter 216 positionedbetween the reconstituted material 212 and the top 214. The filter 216can be made from, for instance, a 3-dimensional open cell structure suchas a foam material. The filter 216 is permeable to liquids butimpermeable to solid particles. The filter 216 can be used to preventthe reconstituted material from entering the beverage.

Of particular advantage, however, capsules can be made according to thepresent disclosure that do not contain the filter 216. In particular,the reconstituted material 212 can be in the form of pellets, sheets,fibrous layers, and the like. For instance, the reconstituted material212 can comprise particles or forms that have sizes greater than 100microns, such as greater than 500 microns, such as greater than 1,000microns. By using larger sized particles or forms, the use of the filter216 can be avoided.

The amount of reconstituted material 212 contained in the capsule canvary. In general, the capsule can contain the reconstituted material inan amount greater than about 1 gram, such as greater than about 3 grams,such as greater than about 5 grams, such as greater than about 7 grams.The capsule can contain the reconstituted material in an amount lessthan about 20 grams, such as less than about 15 grams, such as less thanabout 10 grams, such as even less than about 5 grams.

The reconstituted material of the present disclosure is well suited tomaking teas. In the case of teas or other compositions for use in makingbeverages, the consumer does not need to use a conventional filter paper(tea hag) for preparing the infusion. Specifically, no other accessoryis required (instead of water and a cup or a glass) for making theinfusion.

In one embodiment, the composition offers a high level ofbiodegradability, for example by allowing the composting of tea bags.

In sum, the reconstituted plant products of the invention provideseveral benefits and advantages, such as

the provision of products with higher infusion yield and infusion speed(both with boiling water and water at room temperature);

the provision of a new format to infuse beverages without the need ofpackages and accessories;

the provision of a preferably dispersible and biodegradable product;

the ability to adjust the content of active ingredients (such aspolyphenols, essential oils and the like) to provide a consistentcomposition;

the ability to adjust (reduce) the content of undesired constituents(such as pesticides, caffeine, nicotine, aluminum, heavy metals, and thelike);

the ability to provide new sensory characteristics (such as adjustingintensity of flavor, mixture of various plants and the like); and

reduction of the bacterial load during the manufacturing process.

The following examples further describe and demonstrate embodiments thatare within the scope of the present invention. The examples arc givensolely for the purpose of illustration, and are not to be construed aslimitations of the present invention since many variations thereof arepossible without departing from its spirit and scope.

EXAMPLES Example 1

A tea product was made according to the following method: A black teawas initially heated at 85° C. for 20 minutes with a tea/water ratio of1 to 5 by weight. This was followed by an extraction step in a hydraulicpress to separate the aqueous portion from the tea fiber portion. Therecovered tea fiber portion was again heated at 85° C. for 10 minuteswith a tea/water ratio of 1 to 5 by weight. After an additionalextraction (by pressing), the samples were then refined in a Valleybeater at 1.4% consistency for 10 minutes. After refining, cellulosicfibers (a blend of abaca, hardwood and softwood pulps, with therespective ratios: 60/10/30) were added to the tea fibrous residue witha tea fiber/woodpulp ratio of 5 to 1 in weight in order to make handsheets. The aqueous portion was concentrated in an evaporator to a solidconcentration of 50% and then coated on a hand sheet on a manualsize-press. The soluble level is typically between 27 and 37% in dryfinished product. In example 1, soluble level of the reconstituted teawas approx. 27%, which is the soluble content of conventional tea usedas the starting material of the experiment. The coated hand sheets weredried on a plate dryer.

The product obtained in this example (reconstituted tea; “B20” sample inthe form of discs, containing a coating made by impregnation with teaextract) was tested for its properties in preparing tea and compared toa conventional tea product in tea bags. Both products were used to maketea, and the optical density of the solution (tea) was measured at 274nm. For both samples, the total infusion time in hot water (90° C.) was2.5 minutes which usually corresponds to consumer habit. Same weights oftea material and identical experimental conditions were used: a beakercontaining 200 ml water (ref. Cristaline) was heated at 90° C. At T=0,ie. upon start of the experiment, heating was stopped and the tea bagwas immersed into water. A rotary magnet was used to homogenize thecontent of the beaker during the entire experiment.

Samples of water were taken regulary, every 30 seconds and up to 3minutes. Then, the optical density of the sample was determined using aspectrophotometer at the wavelength of 274 nm (maximum absorption ofcaffeine). The reference/blank test was run with a sample of clear water(Cristaline) heated at 90° C.

The optical densities measured (after 3 minutes of infusion) for thereconstituted tea product were 0.69, whereas for the conventional teabag 0.63 was measured. The result is graphically shown in FIG. 1 . Thus,for reconstituted tea (B20), a higher infusion rate of solubles wasobtained as with the conventional product in tea bags. The extractionratio in this test was +10% as compared to the conventional product intea bags. The reconstituted tea enabled a more efficient infusion (100%solubles are extracted from the plant); using the same amount ofmaterial, more solubles could be released from reconstituted tea thanfrom natural tea.

Similar results were obtained with different infusion times, or whenreconstituted tea was compared to tea in loose form. Also, similarresults were obtained with reconstituted products made from herbs ascompared to conventional herbal tea products.

Example 2

The product of example 1 (B20) was used to determine the infusion rateas compared to conventional tea in tea bags.

The optical densities were measured over time. The experimental set-upwas identical to example 1. For the reconstituted tea product, anoptical density of 0.6 was reached within 20 seconds from contacting thesame with water, whereas about 2 minutes were required to obtain thesame optical density using the conventional tea bag. The result isgraphically shown in FIG. 2 .

The example demonstrates that the reconstituted tea product providesfaster infusion than conventional tea in tea bags.

Similar results were obtained when reconstituted. tea was compared totea in loose form. Also, similar results were obtained withreconstituted products made from herbs as compared to conventionalherbal tea products.

Example 3

The product of example 1 (B20) was used to determine its infusionproperties at different temperatures as compared to conventional tea intea bags.

As in example 2, the optical densities were measured over time. Theexperimental set-up was identical to example 2, except for the fact thatwater at room temperature (20° C.) was used instead of hot water (90°C.). For the reconstituted tea product, an optical density of 0.3 wasreached within about 30 seconds (0.6 within about 2 minutes) fromcontacting the same with water, whereas the conventional tea bagrequired about 6 times longer to provide the optical density of 0.3. Theresult is graphically shown in FIG. 3 .

The example demonstrates that even in cold water the reconstituted teaproduct provides faster infusion than conventional tea in tea bags. At20° C., the extraction ratio after 3 minutes of infusion is much betterthan standard product (+100%). Also, the extraction ratio of thereconstituted tea material at 20° C. is similar to the extraction ratioat 90° C.

Similar results were obtained when reconstituted tea was compared to teain loose form. Also, similar results were obtained with reconstitutedproducts made from herbs as compared to conventional herbal teaproducts.

Example 4

The following example demonstrates that the delivery of solubles andactive ingredients can be easily adjusted in the manufacturing process(either decreased or increased as compared to a given standard).

As control, a conventional tea was used containing solubles in an amountof 26% (w/w). The soluble content was measured by determining the weightof a given sample before and after extraction. In a separate experiment,a portion of the same tea was subjected to a manufacturing processsimilar to example 1. The amount of solubles was adjusted in threedifferent runs to 5% (w/w; decreased level), to 26% (w/w; standardlevel) and to 50% (w/w; increased level) by adjusted the coating ratioduring impregnation.

The experiment demonstrates that the reconstituted product can be usedto provide a consistent, standardized delivery level of soluble/activeingredients as compared to the natural products that generally show aninherent variability.

Example 5

Following the method disclosed for the product of example 1 (B20),similar products were obtained and tested. In these tests, differentreconstituted tea products, i.e. reconstituted material constituted bythe base web impregnated with the solubles portion of the originalmaterial, were produced and compared to conventional tea, either inloose form or in the form of tea bags. The reconstituted tea productsvaried in the solubles coating ratio, i.e. the amount of solubles coatedonto the base web of reconstituted tea (dry basis weight ofreconstituted plant material in g/m²).

The following products were prepared and tested:

Amount of solubles Sample (=coating ratio for # Description Format Drybasis weight reconstituted samples) 1 Original vegetal, Loose na Around30% unwrapped 2 The same vegetal as above Tea bag na Around 30% but intea bag (same plant (double and same origin, as 1) chamber) 3 Standardreconstituted disks Standard (100 gsm) Same as original vegetal vegetal(same plant and (30%) same origin as 1 & 2) ie new delivery device 4Adjusted reconstituted disks standard Decreased vs standard vegetal(same plant and (20%) same origin as 1 & 2) 5 Adjusted reconstituteddisks standard Increased vs standard vegetal (same plant and (50%) sameorigin as 1 & 2) 6 Adjusted reconstituted disks Decreased vs Same asoriginal vegetal vegetal (same plant and standard (60 gsm) (30%) sameorigin as 1 & 2)

Specifically, sample #3 was compared with samples #1 and #2; sample #3was compared with samples #4 and #5; and sample #3 was compared withsample #6.

The comparison of the properties of the products similar to theexperiments performed in examples 1 to 4 confirm the results in examples1 to 4, namely that reconstituted tea provides a better ratio ofextraction and faster extraction, even at low temperature (water at roomtemperature) and allows to adjust the amount of solubles/activeingredients released upon infusion.

Example 6

Tea bags were made from tea material, which was mixed in various batcheswith a blend of cellulose fibers (abaca, hardwood and softwood pulps,with the respective ratios: 60/10/30). As in example 1: a black tea wasinitially heated at 85° C. for 20 minutes with a tea/water ratio of 1 to5 by weight. This was followed by an extraction step in a hydraulicpress to separate the aqueous portion from the tea fiber portion. Therecovered tea fiber portion was again heated at 85° C. for 10 minuteswith a tea/water ratio of 1 to 5 by weight. After an additionalextraction (by pressing), the samples were then refined in a Valleybeater at 1.4% consistency for 10 minutes. After refining, cellulosicfibers (a blend of abaca, hardwood and softwood pulps, with therespective ratios: 60/10/30) were added to the tea fibrous residue atvarious levels in order to prepare the different samples and make handsheets. Hand sheets were later dried on a plate dryer.

It is possible to make tea bags from a fiber web produced with anadjustable proportion of tea fibers or herb fibers (from 5% to 80% ofthe total weight), mixed with cellulosic and/or synthetic fibers. Theproportion of tea or herb fibers can be distinctively high.

During the first trial, the ratio of tea/cellulosic fibers was 40/60(w/w); in a second trial the ratio was 60/40 (w/w) and in a third trial,the ratio was 80/20 (w/w). The fibrous web used for making the tea bagswas not impregnated but the tea bags were filled with tea (taken fromconventional tea bags). Their infusion performance was compared toconventional tea bags containing the same amount of tea. Themeasurements were similar to examples 1 and 2.

The infusion performance of the sample corresponding to the 80/20 ratio(Trial C1) matched with the infusion performance of conventionalcellulosic tea bags (control) as measured by optical density. The resultis graphically shown in FIG. 4 .

Example 7

In another trial, the fiber web used for making the tea bags of example7 was impregnated with tea extract obtained in the extraction stepcoming from starting material. The tea bags were additionally filledwith tea. The amounts of coating varied from 5% to 50% of the totalweight.

In separate tests, fiber webs were made from tea (Camellia sinensis) orherbs used for producing herbal teas.

Infusion performance was measured and compared to conventional teabags/herbal tea bags containing the same amount of tea/herbal tea. Themeasurements were similar to examples 1 and 2.

Again, more solubles were released, and infusion rates were faster forthe reconstituted, impregnated tea bags than for the conventional teabags due to the additional release of tea soluble from the coating, inaddition to natural infusion coming from the tea which is contained inthe bag. The additional delivery of solubles provides a distinctivestronger taste.

In one trial, an tea bag was made from tea, impregnated with tea extractas described above in this example. In infusion tests using water at 90°C., the product released 35% (w/w) tea solubles into the water.

Example 8

In one experiment, two different products were produced: product C1 inthe form of a tea bag, containing about 5% solubles (w/w), with a drybasis weight of approx. 120 g/m² (w/w) and product B20 in the form of atea bag, containing about 5% solubles (w/w), with a dry basis weight ofapprox. 60 g/m² (w/w). The tea bags were not filled with tea.

Infusion performance under identical conditions was measured andcompared for samples C1 and B20 similar to examples 1 and 2. The resultswhich are graphically shown in FIG. 5 demonstrate that the release oftea solubles can be also driven by the basis weight of the finishedproduct.

Example 9

Example 1 described above was repeated with the additional use of a wetstrength agent (here: cationic polyamide amine resin), in order toreduce potential degradation of some of the reconstituted material inwater. The wet strength agent was added to the fibrous portion.

A tea product was made according to the following method: A black teawas initially heated at 85° C. for 20 minutes with a tea/water ratio of1 to 5 by weight. This was followed by an extraction step in a hydraulicpress to separate the aqueous portion from the tea fiber portion. Therecovered tea fiber portion was again heated at 85° C. for 10 minuteswith a tea/water ratio of 1 to 5 by weight. After an additionalextraction (by pressing), the fibrous portion was then refined in aValley beater at 1.4% consistency for 10 minutes. After refining,cellulosic fibers (a blend of abaca, hardwood and softwood pulps, withthe respective ratios: 60/10/30) were added to the tea fibrous residuewith a tea fiber/woodpulp ratio of 5 to 1 in weight and a wet strengthagent was then added to the fibrous portion at a level of 5% w/w inorder to make hand sheets. The aqueous portion was concentrated in anevaporator to a solid concentration of 50% and then coated on a handsheet on a manual size-press. The soluble level is typically between 27and 37% in dry finished product. In this example, soluble level of thereconstituted tea was approx. 27%, which is the soluble content ofconventional tea used as the starting material of the experiment. Thecoated hand sheets were dried on a plate dryer.

Example 10

In order to determine the effect of reconstituted tea soluble contentand the dry basis weights on the infusion profile, a tea product wasmade according to the following method: A black tea was initially heatedat 85° C. for 20 minutes with a tea/water ratio of 1 to 5 by weight.This was followed by an extraction step in a hydraulic press to separatethe aqueous portion from the tea fiber portion. The recovered tea fiberportion was again heated at 85° C. for 10 minutes with a tea/water ratioof 1 to 5 by weight. After an additional extraction (by pressing), thefibrous portion was then refined in a Valley beater at 1.4% consistencyfor 10 minutes. After refining, cellulosic fibers (a blend of abaca,hardwood and softwood pulps, with the respective ratios: 60/10/30) wereadded to the tea fibrous residue with a tea fiber/woodpulp ratio of 5 to1 in weight and a wet strength agent was then added to the fibrousportion at a level of 5% w/w in order to make hand sheets. The aqueousportion was concentrated in an evaporator to a solid concentration of50% and then coated on a hand sheet on a manual size-press. The solublelevel is typically between 27 and 37% in dry finished product. In thisexample, the following products were prepared:

Product A: soluble level of the reconstituted tea was 22%, which is thesoluble content of conventional tea used as the starting material of theexperiment. Dry basis weight of the material was 70 grs per m² (drybasis);

Product C: soluble level of the reconstituted tea was 22%, which is thesoluble content of conventional tea used as the starting material of theexperiment. Dry basis weight of this material was 170 grs per m² (drybasis) which is 143% higher than A;

Product D: soluble level of the reconstituted tea was 38% which is 73%higher than A. Dry basis weight of D material was 170 grs per m² (drybasis) also

The coated hand sheets were dried on a plate dryer.

The products (A, C and D) obtained in this example were tested for theirproperties in preparing tea and compared. Both products were used tomake tea, and the optical density of the solution (tea) was measured at274 nm. For all samples, the total infusion time in hot water (90° C.)was 5 minutes. Same weights of tea material (2.5 grs) and identicalexperimental conditions were used: a beaker containing 500 ml water washeated at 90° C. At T=0, ie. upon start of the experiment, heating wasstopped and a tea strip was immersed into water. A rotary magnet wasused to homogenize the content of the beaker during the entireexperiment.

Samples of water were taken regularly and up to 5 minutes. Then, theoptical density of the sample was determined using a spectrophotometerat the wavelength of 274 nm (maximum absorption of caffeine). Thereference/blank test was run with a sample of clear water heated at 90°C.

The result is graphically shown in FIGS. 8 and 9 .

FIG. 8 : Reconstituted tea (D—high soluble content) shows a higherinfusion level of tea solubles than C (standard soluble level). In orderto reach an infusion level of 8.3 (expressed by 10× optical density at274 nm), it takes 300 sec with sample C whereas only 40 sec are neededfor D material (87% faster). Sensory evaluation performed by tea panelgroup also showed a stronger tea flavor and taste with D than with Cafter 5 mins infusion. This demonstrates that tea infusion taste can beadjusted thanks to soluble content of reconstituted tea material.

FIG. 9 shows that Reconstituted tea A with a lower basis weight shows afaster infusion level of tea solubles than C. Figures show that infusionrate of 8.3 (expressed by 10× optical density at 274 nm) is reached in120 sec for A sample whereas 300 sec are needed for C. Infusion with Ais 60% faster than with C. Actually, a lower basis weight for a givenweight of material entails a more important contact surface which, atthe end, improves infusion kinetics.

Example 11

In order to determine the effect of the reconstitution process on thegreen tea infusion sensory profile, a tea product was made according tothe following method: a green tea (Sencha from China) was initiallyheated at 85° C. for 20 minutes with a tea/water ratio of 1 to 5 byweight. This was followed by an extraction step in a hydraulic press toseparate the aqueous portion from the tea fiber portion. The recoveredtea fiber portion was again heated at 85° C. for 10 minutes with atea/water ratio of 1 to 5 by weight. After an additional extraction (bypressing), the fibrous portion was then refined in a Valley beater at1.4% consistency for 10 minutes.

After refining, cellulosic fibers (a blend of abaca, hardwood andsoftwood pulps, with the respective ratios: 60/10/30) were added to thetea fibrous residue with a tea fiber/woodpulp ratio of 5 to 1 in weightand a wet strength agent was then added to the fibrous portion at alevel of 5% w/w in order to make hand sheets. The aqueous portion wasconcentrated in an evaporator to a solid concentration of 50% and thencoated on a hand sheet on a manual size-press. In this example, theproduct was produced at 36% extract content, which is the solublecontent of the starting material. of the experiment. The coated handsheets were dried on a plate dryer.

The product obtained in this example was tested for its sensoryproperties and compared to natural tea material used for the experimentas described above. Both products were used to make tea. For allsamples, the total infusion time in hot water (90° C.) was 5 minutes.Same weights of tea material (2 grs) and identical experimentalconditions were used: a beaker containing 200 ml water was heated at 90°C. and tea materials were immersed into water. Then, after 5 minutes,sensory profile of both products was performed. The result isgraphically shown in FIG. 10 .

The experiment shows that the odor, color and taste are higher in thereconstituted tea than the natural material. However, astringency andbitterness are significantly lower in the reconstituted tea than naturalmaterial.

Removal of Caffeine from Tea Leaves Thanks to the Reconstitution Process

In order to illustrate the potential of the invention to reduce theamount of specific components from tea, a treatment to decrease caffeinecontent from tea was developed and tested at the lab scale.

Literature shows that alkaloids compounds such as caffeine are extractedin the soluble portion. Therefore, experiment has been run on the liquorpart of tea, after separation step.

A black tea was initially heated at 85° C. for 20 minutes with a teawater ratio of 1 to 5 by weight. This was followed by an extraction stepin a hydraulic press to separate the aqueous portion from the tea fiberportion. The aqueous portion of tea was then mixed with activatedcharcoal in powder form. Approx. 23 g of activated charcoal was added to500 ml of tea liquor and mixed at 60° C. stirred at 350 rpm for 1 hour.After filtration, caffeine levels in liquors were measured then throughLC-MS method.

The following samples were produced:

-   -   Control: standard tea liquor without activated charcoal        treatment    -   A: Tea liquor treated with activated charcoal Acticarbone P13        from CECA    -   B: Tea liquor treated with activated charcoal Acticarbone 2SW        from CECA    -   C: Tea liquor treated with activated charcoal Acticarbone 3SA        from CECA    -   D: Tea liquor treated with activated charcoal Acticarbone CPL        from CECA

Caffeine contents in tea liquors are as follows:

-   -   Control: 22700 mg/Kg    -   A: <10 mg/Kg    -   B: <10 mg/Kg    -   C: <10 mg/Kg    -   D: <14 mg/Kg

It can be seen that caffeine levels are strongly reduced by usingactivated charcoal on tea liquor.
